This is the second volume of hearing transcripts and exhibit copies published by the Subcommittee on Intelligence and the Rights of Americans of the Select Committee on Intelligence of the United States Senate (Church Committee). These hearings on the "Huston Plan" were held September 23-25, 1975, and the transcripts were published in 1976.
This copy of the document was obtained from the U.S. Senate Select Committee on Intelligence web site: http://www.intelligence.senate.gov/pdfs94th/94intelligence_activities_II.pdf
. It is not a complete copy, as it is missing the following pages: 164, 170, 300, 302, and 308. A copy of the document with those pages included (which are completely redacted) may be found here: http://www.aarclibrary.org/publib/church/reports/vol2/pdf/ChurchV2_4_Exhibits.pdf
